i just got my cat-converter from UPS today. before i install it do i need to get new O2 sensors or will my stock ones work with it? i dont wanna fawk anything up

 

describe ur car year and model? cars with above 60K are recommended to change out o2 sensors, but then again, if it aint broken, dont fix it rule can apply also, basically if u dont have a CEL why change it. did u get a high flow or an OEM catalytic converter?

 

UPS makes cat converters!? :P

Send it back and get a high flow cat w/o O2 sensor.

Live on the edge

 

I do have a HI-FLOW cat converter it is not oem!!! it doesnt have an o2 sensor either thats a good thing rite?
